This Coast to Coast SAE male x BSP female union 5/16" x 3/8" steps a gas line from 5/16" SAE to 3/8" BSP without changing the rest of your setup. The straight union layout suits short joins between regulators and appliances over 50–150 mm of pipe. You can use it across caravan and RV gas gear that already runs 2.75–3.0 kPa LPG systems and standard hose sizes.

The union uses a female gas union body with a 3/8" BSP inlet and a 5/16" SAE male outlet sized for common LPG fittings. The hex body works with standard spanners around 14–19 mm wide so you can nip it up firmly without special tools. Coast to Coast supplies this 01-1610 connector as part of their caravan gas fittings range for Aussie touring setups.

Q: Can this union connect a 5/16" SAE gas hose to a 3/8" BSP fitting?

Yes, that is exactly what it is for. One end is a 5/16" SAE male thread that suits matching SAE hose or tube fittings. The other end is a 3/8" BSP female thread for standard BSP gas hardware. This makes it handy when your appliance tail and fixed pipework use different thread standards.

Q: Is this union suitable for caravan and RV LPG setups?

Yes, it is listed for caravan and RV gas fittings. The 5/16" SAE and 3/8" BSP sizes are common on van regulators, hoses and appliances. Using a purpose made gas union keeps thread engagement correct compared with using makeshift adapters. Always follow gas regulations and have licensed gas work where required.

Q: Is this a straight connector or an elbow?

This part is a straight union. The fitting lines the SAE and BSP connections in a single axis rather than changing direction. Straight unions are useful where you just need a simple join between two runs. If you need to turn a corner you would use an elbow instead of this part.

Q: Do I need special tools to fit this union?

No, standard spanners will usually do the job. The hex body is sized so you can grip it with common open-ended or adjustable spanners. Correct tool sizing helps avoid rounding the flats. Always avoid over-tightening and check for leaks according to gas safety practices.
